Which statement is true about selective breeding and genetic engineering? A) Both genetic engineering and selective breeding aim to develop crops with desirable traits.
B) In genetic engineering, only traits that are natively found in the genome of the species can be
isolated and expressed.
C) In selective breeding, the desired genes can be directly manipulated or inserted into the DNA of
the organism.
D) In selective breeding, the potential list of insertions is not limited to those natively found in the
organism.

the limb fractures are among the most common fractures. open fractures are comparatively more dangerous. the injury patterns are dependent on many factors, such as the age of the person, and mechanism of the injury. the closed fractures of the limbs if left untreated may lead to a significant amount of the blood loss, which may be life-threatening for the person. approximately 1000-1500 ml of blood is lost in the close fracture of the femur, and 500-1000 ml of blood is lost in the closed fracture of lower part of the limbs.

during expiration the diaphragm relaxes, which causes the diaphragm to move downwards. the contraction of diaphragm increases the space for expansion of lungs. hence, the diaphragm relaxes and positioned downward during expiration.
